NAIL-SETTING MACHINE. I

- To all whom it may concern Be it known that I, NICHOLAS DEDRIGK, ofManltowoc, Hsconsm, have invented a Nail-Setting Machine, of which thefollowing is a specification. i

This invention is a device for a special purpose which can be brieflydescribed as follows: In the manufacture of purses, the material of thepurse consisting of leather or the like hasits edge riveted. toa metalframe which forms the closure member of the purse. The metal frameconsists of a border of sheet metal through which and the edge of theleather rivets are placed; a second strip of sheet metal to holdtheupset ends of the rivetsfrom tearing through the leather is placed onthe inside, and the rivet upset over this strip. The rivets consistoriginally of small round-headed pointed nails theendsof which, afterthey are set in place are cut off by nippers and the nails then upset.Heretofore this operation has been performed entirely by hand.

The object of the presentmachine is to provide means for setting thenails in place ready for cutting off and riveting- Nails are ordinarilyautomatically fed froma pile one by one to a holder, picked up by saidholder and held pointed end up upon an anvil while the material,consisting of the frame, leather and riveting-strip are pressed downover the point. I also provide means for automatically causing. the nailto. be

V thrust through the material.

The apparatus is illustrated in the accompanying drawings, wherein'Figure 1 is a'front-view .of a complete machine, the bench or tableupon which it stands being shown in section; Fig. 2. is a side-viewthereof, some of the parts at the rear of the view being omitted toavoid confusiong Fig. 3 is a longitudinal section on the plane 3,showing the hammer depressed ations; Fig. 7 is a sectional elevation onthe plane 7 Fig. 8 is a fragmentary sectional elevation on the plane 8;Fig. 9 1s a sectlonal Specification of Letters Patent.

The apparatus is mounted. on. a plate shaped base A provided withscrew-holes a through which may be inserted screws a (see Fig. 7)whereby it may be secured toa bench or table B. The bench or table isherein shown in section and is provided with a hole 12 bored in it,through which extends the lower end of a tubular standard C, whichismounted and supported upon the plate A. As shown in Fig. 3, the tubularstandard C is 'providedwith-ashoulder c on the underside of the plate A,and with a, 4

thread 0 above it, which is. engagedby a the threaded stud, and ofcourse suitably keyed so that it cannot turn on the shaft. A member F isintercalated between the nut (Z and the carrier E, as shown, forpurposesherei'nafter explained. In its position of rest, shown in'Figs.1', land 3, the swingv,

arm E comes to'rest upon the upper end of the tubular standard C and thelatter forms an abutment therefor. Standard C is rabbeted around itsupper edge to receive an annular cushion c of fiber or like material.

The carrier E performs the function of conveying the nails one by onefrom the nailholding magazine G on the left of the manut 0 securelyclamping the standard in chine and the auxiliary devices whereby thetacks are taken one by one from said magazine and delivered to thecarrier (or swingarm) E, and by it brought to the anvil H at the frontof the machine; and the nail I is held on the anvil by the carrier (seeFig. 3) during the operation of forcing the point of the nail I throughthe leather J of the purse. For the purpose named the carrier E isprovided on its free end with a fixed nail-holding blade or finger e anda movable nailholding blade or finger 74 the finger e being secured byscrews 6 to the end of the member E, and the finger being secured byscrews is to the member K which is pivoted upon a pivot-screw 70 so thatsaid fingers e and 70 act together in the manner of a pair of shears ortongs to hold the nails I. The member K has an arm 70 which extendsrearwardly and is connected in a yielding manner to the body Of thecarrier E by means of a small spring 713 attached to posts 6 and on themembers E and K respectively. The left-hand or movable finger 70 alsohas in its front end a small notch in", leaving between it and thefinger k a recess slightly smaller than the shank of the nail, wherebythe nail is held with sufficient firmness for the purpose in Viewthrough the action of the coiled spring is. That is to say, this is thecase when the carrier E is presented to the nail-placing devices whichdeliver a nail to the fingers and during the carrying-movement when thecarrier is returning to its position on the anvil, that is to say, fromthe position shown in Fig. 5 to the position shown in Fig. 4:; but, inthe latter position, the spring k alone is not relied on to hold thenail I in place during the operation of forcing the nail through theleather, but the member K is also held in a position to hold the fingerk firmly against the nail by a spring-bolt m which is mounted upon astandard or post M at the right of the carrier. The springbolt m ispressed forward by a coiled-spring m (see Fig. 12) which is compressedwithin the bore in which the bolt on is mounted and abuts against thebolt m at one end and against the headless-screw m at the other. Across-bar m traversing the bolt m and a pair of slots m on oppositesides of the bolt, limits the movement of the latter. The end of thebolt m is chamfered or cut-off obliquely from the top down for thepurpose of enabling the arm 70 to push the bolt back when it descends asthe carrier E resumes its position uponthe anvil; for it is to beunderstood that the carrier E and shaft D do not merely turnhorizontally upon the axis of the shaft, but they also have aconcomitant vertical movement, which is effected in the followingmanner: In the lower part of the tubular standard C, which is below theplate A, arecut two oppositely disposed cam-slots 0 said slots havingtheir lower ends vertical, that is to say, parallel to the axis of theshaft, their intermediate portions helical, and their upper ends againvertical, as clearly shown in the several figures of the drawing. lViththese cam-slots cooperate a pair of rollers (Z which are mounted uponpivot-screws (Z which are screwed into the opposite sides of the shaftD. Now, it will be seen that the weight of the apparatus causes theshaft D, carrier E and attached parts to assume normally the positionshown in Figs. 1, 2, 3 and 7, in which the carrier rests upon the anvilH, the shaft Dis at the lower end of its movement, and the rollers clare in the vertical lower end-portions of the cam-slots 0'. Now anupward pressure upon the lower end of the shaft D, effected ashereinafter described, will cause said shaft and the carrier E first torise vertically, until the rollers (l strike the helical intermediateportions of the slots 0*"; and thereupon the carrier and shaft will becaused to continue the rising movement with a rotation added thereto,and this will be continued until the carrier E reaches the positionshown in Fig. 5, that is to say, reaches the limit of its rota tionalmovement; the rollers (Z now strike =3 the vertical upper end-portionsof the slots 0 and the carrier E will be given a vertical upwardmovement, bringing it into the dotted-line position shown in Fig. 7.Contrariwise, when the carrier E returns to its original position itwill first descend, then swing around to a position immediately over theanvil, and finally descend to a position of rest as hereinbeforedescribed; and, in

this movement, the end of the arm 70 strik TH ing the beveled end of thebolt m will press back the latter so that the bolt will exercise itsforce upon the end of the arm 72 to hold the nails in place between thefingers e and 7: as the carrier comes to a position in which the head ofthe nail I rests on the anvil.

The nail-magazine G, which is illustrated in detail in Figs. 8 to 11inclusive, comprises an upright tubular post 9 which is mounted on theplate A, as for example by having a 3 plug fixed in its lower end boredand threaded to engage with a screw 9 or any other suitable arrangement,and carries at its upper end a hopper 9* which receives the nails. Saidhopper is for convenience provided with a movable cover 9 which ispivoted upon an upright post 9 at one side thereof, and to hold it inplace a coiled compression-spring g is disposed upon the post 9 abovethe cover 5 and is held in firm abutment with the latter by means of aset collar 9 clamped by a screw 9. The cover 9 may have a handle and apair of ears or clips g on opposite sides which engage the sides of thehopper g to keep the cover in place. Within the tubular post g ismounted a sliding member said member being preferably flattened and thepost flattened correspondingly so as to format close guard therefor.

In it upper end the sliding member 9 is longitudinally slit paralleltoits broader side by a narrow deep recess 9 the width of which is justsufficient to admit the shanks of the nails but not their heads. It willbe seen from Fig. 9

that the upper end of the member 9 is cut end thereof as shown in Fig.9, being sup-.

ported by their heads, and the shanks of the nails depending in theslotg. In this position the ends of the slot are closed by the sides of thepost 9 and continuations of" said sides are formed by the upright bars gand g, whose opposing edges are concaved as shown, so as to formeffectively guides for the member y when it is raised. On the higher orright-hand side of the sliding member 9 the post 9 is carried up to thetop of the hopper, but on the left-hand side the post 9 is connectedwith a sloping chute g, which has a slot g" forming a continuation ofthe slot 5 and the upper edge of said chute forms a continuation of theupper edge of the member 9 when in its raised position, so that anynails I which are caught in said slot 9 when the member g is in itslowered position are, when the member is raised, released and slide downthe chute g until they reach the end thereof as shown in Fig. 9, saidchute passing through the wall of the hopper g and the end thereof lyingoutside the hopper. At this point, the further'movement of'the nail isbarred by a pair of small. springfingers 9 secured to the outer side ofthe chute and hopper g in such manner that they project over the ends ofthe chute (see Fig. 11). In order to prevent the nails which are caughtin'the slot 9 :from being thrown out of it over the top as the member issuddenly checked in its rising movement, another pair of spring-fingers9 secured to the opposite sides of the post g (see Fig. 11), are sodisposed as to project over and close to the upper end of the mem-.

her 9 when in its raised position, thereby checking any such jumpingmovement of the nails.- The reciprocating movement of V the member g iseffected by means of an arm N. the end of which projects through a hole9 in the lower end of the member 9 slots 9 being also formed in theopposite sides of the hollow post g to enable the arm N to move up anddown freely. Said arm N (see Figs. 5, 6 and 7 is pivoted upon a pin 17.in a post n mounted on the plate A, and its rising movement isefl'ectuated by means of the member F already referred to, which ismounted upon the stud'olhof the shaft Dimmediately over the carrier E,said member F having, as clearly shown in Figs.

1 and 7, two arms 7 and f, the former of which is bent up and the latterdown. The downwardly bent arm 7 has a laterally proj ecting toe 7, whichis chamfered or beveled on its upper face as clearlyshown in Fig. 6, andis so placed that when the carrier .E turns upon its axis, the arm fturning with it causes the toe f toengage under the mem-.

ber N, and in the final vertically upward movement of the carrier thisengagement causes the arm N to be raised and thus to raise thereciprocating member so thatat each cycle of operations one or morenails will be carried=from the bottomof the hopper and, delivered intothe chute 9 and thence slide to the lower end thereof, where they areready to be delivered to the devices which will now be described forplacing the nails between-the fingers of the nail-holder or tongs.

As will be seen from Figs. 7, 8 and 9, the lower end of the chute 5/projects outside the hopper and into a position directly under avertically reciprocating detaching pin O, mounted to reciprocate in thehollow post 9. The vertical movement of this pin is limited by atransverse pin' o ,v which is set in the pin 0 and the ends of whichproject into slots 9 in the sides of thepost 9 where the latter projectsbelow the wall of the hopper 9 The lower end of thispost g is alsowidened and boredto receive the upper end 22 of the nail-reversingmember P, said memberbeing secured in place by a setscrew 9 Themember 'Pis hollowed out interiorly and is set opposite the end of the chute and,as will be seen from Fig. 9, the hollow-interior chamber 9 of saidmember extends above the head of the adjacent nail which is suspended atthe lower end of the chute, but there is a crossbar p which bly thrownover into the chamber 79 Normally the pin 0 is supported in a yieldingmanner by the coiled compression-spring 0 surrounding its upper end andrestingupon the collar 9 or upper end-of the post and upon a cross-pin0. The depression-movement of the pin 0 is effected by the upper end ofthe arm 7 of the member F, which, as plainly seen in Fig 1, projects inthis position over the upper end of the pin 0, and it carries aset-screw f and lock-nut f by which the amount of depression of themember O can be nicely regulated. It will be understood, of course, thatthe actual depression takes place on the return-movement of the carrieras it comes back to its position over the anvil and descends verticallythereupon.

Directly under the member P there is mounted a hollow post Q, which issecured to the base-plate A by a screw g threaded into the lower endthereof, or by any other suitable means. This post Q contains areciprocating plunger 9 which has an enlarged head Q3 on its lower end,this end being slotted transversely to receive the end of an arm R whichreciprocates in lateral slots 9* in the post Q, and is pivoted upon apivot-pin Won the upper end of a post r mounted on the base A. The upperend of the post Q is interiorly threaded to receive a tubular head Q5,the bore of said head'being just sufficient to admit a nail I thereintoas shown, and as the upper end of the plunger 9 projects into said bore,it will be understood, of course, that it has the same diameter. Withinthe post Q, surrounding the plunger 9 and having an abutment at one endupon the head 9 and at the other upon the head 9 is a. coiledcompression-spring 9 which acts to assist the force of gravity inreturning the plunger Q3 to its lower position as shown in Figs. 7 and9.

The nail I does not fall from the reversing-box P directly into thetubular bore of the head but into a funnel 8 which is mounted on theswing-arm S, pivoted on a pivot-screw s mounted on the upper end of thepost 8 Said funnel 8 acts as a guide to carry the nails head-downwardinto the upper end of the post Q. The arm S has a swinging movement uponthe end of the post 8 through a small angle, and it is kept yieldinglypressed forward by a coiled torsion-spring 8* (Figs. 1 and 7) having oneend engaging in a hole near the base of the arm S and the other end in asupportingcollar 8 which is secured to the post 8 by a set-screw s. Thepost 8 is mounted upon the plate A and may be secured thereto by a screw3 threaded into its lower end as shown in Fig. 7 The forward travel ofthe arm S is limited by an abutment-block 5- which strikes against theside of the head in a position in which the funnel s is in exactregistry with the bore of the head Thus it will be seen that when thepin 0 is depressed in the manner aforesaid, the nail I at the bottom ofthe chute will be thrown off, and being tripped by the bar 77" is turnedhead down and so falls into the funnel s by which it is guided so thatit lands in the bore of the head as shown in Fig. 9. Now, in order thatthe nail I which has been delivered into the bore of the head 9 may bedelivered between the fingers 6 and is when they are brought by therotational movement of the carrier E into a position in which the notchk is directly over the bore 9 the funnel s is set upon the movable arm Sso that it can be swung out of the Way, and this swinging movement ofthe arm S is efiectuated by devices carried on the carrier E and bestillustrated in Figs. 3 and 7, and their action best illustrated by theplan-view, Fig. 5. The pivotscrew 70 which forms the pivot of the member K is extended downwardly as shown in Fig. 3 to form also the shaftor aXis of the roller 0 which is secured in place by a nut e engagingthe threaded lower end of the member 70 This roller 6 is so disposed asto strike the front side of the arm S when the carrier E swings aroundandto swing said arm S backwardly,as shown in Fig. 5, until the endthereof comes to abut upon the side of a downwardlyprojecting piece asecured to one side of the carrier E by a screw 6 Such abutment limitsthe swinging movement of the carrier E as well as of the arm S. Now, aswill be seen from Figs. l and 5, the arm S forms one of a pair ofguide-fingers, S, 8 both pivoted upon the pivot-screw s and held yieldingly together by the coiled-spring s which is hooked into the eyesof a pair of posts 8 and s mounted respectively on the. members S and 8.At a point on the line between these two members S and 8 which isimmediately over and in registry with the bore of the head wnen theparts are in the positions shown in Fig. 5, they are notched out to formthe conical hole .9 one-half of the hole forming a semi-conical notch ineach piece, so that the pointed end of the nail I, and following it thehead thereof and the upper end of the plunger Q2, can be pushed upthrough the conical-hole s and in so doing spread the members S and s"so as to give passage to the head of the nail and the upper end of theplunger 9 The hole 8 acts, therefore, as a guide to hold the nailupright while it is passing from the boreg into the notch between thefingers e and 70 On the carrier E opposite the abutment-piece e andsecured by the same screw, 0 is a downwardly extending member 6 having atoe a bent horizontally at right angles to the lower end thereof (seeFig. 7). The toe e is adapted to take under the arm R- as the carrier Eswings around, and as the latter rises it will also raise the arm R, sothat" by the time the carrier has reached the limit of its rotationalmovement the arm R will have raised the plunger Q2, and the nail Isupported thereby, sufliciently so that the end of the nail will beready to pass into the notch is between the fingers s and 71: The finalvertical rising movement of the carrier heretofore described, and whichnow takes place, causes the arm R to be raised sufficiently to.bring-the nail I into the position I shown in dotted lines in Fig.7,where it has been thrust between and is supported by the fingers e 70 Onthe return-movement a vertical drop first takes.

place, in which the plunger 9 will drop below the 'member S, and themembers S "and s will come together again so as to close the hole 8 Thehead of the nail I now being-above the member S and over the "small endof the hole 8 can no longer pass through the latter so that in strikingthereupon it is thrust farther upward between the fingers e and 731,until the latter supportit directly under the head as they start ontheir return movement. Of course," if the nail should not have beenpressed quite up "to the head between the fingers e and 70 it will be sopressed whenthe latter come down upon the anvil H.

The apparatus as thus far. described is sufliciently complete in itselfto be operated so far as the operation of taking the nail and setting itin position or thrusting it through the leather is concerned. However,

in the most improved form of my apparatus,

I prefer to provide means whereby the nail can be mechanically thrustthrough the leather, which is particularly advantageous where theleather is thick, andthe point of the nail rather blunt. Suchmeans'consist of a hammer the point of which is hollowed to receive thepoint of the nail, and which therefore strikes only upon the leather orrather upon the perforated metal late which is placed over the leather,-an not upon the nail itself. This construction, best illustrated inFigs. 2 and 3,'is asfollows: The shaft D is longitudinally bored toreceive a rod T, which 'at its upper end is screwed into a bored andthreaded headpiece t as shown, and the shaft Dis chambered out at d toreceive a coiled compresof the hammer-arm U, where it passes through theslot 25 of member t, has a parallel-sided slot to receive a roller iwhich turns. upon a pin 6 mounted in the end of the, member t andprojecting across theslots t and w. This arrangement constitutesefiective' means whereby, on the depression of-the rod T, the hammer-armU is carried downwardly into the position shown in full lines'in Fig.'3; The front or free end of the arm U carries a. heavy "hammer-arm'Uisdepressed. V

As accessory apparatus, an achustable weight a and is turned downwardlyas shown at u and the end'thereof longitudinally bored as shown atu, anddisposed in such a position that the nail I which is held between thefingers 6 audit will pass into the bore a when the member U isdepressed.

As an additional guide for the hammer-arm' U, a post WV is mounted onthe carrier'E in front of'the member 6 and is slotted at w to receivethe hammer-arm U and has a cushion at its lower end in'the form of afiber-strip 'w for an abutment when the guide is. provided for thematerial ofthe purse, said guide consisting of the curved standard X,whichis'clamped to the inner face of the anvil H' by a thumb-screw 00one edge thereof abutting against the pin m and its upper end being benttothe rear as shown at 02 Fig. 2', and-the guideme1nber w beingadjustably secured thereto by screws 00 passing through slots 00 in theend m of the'standard, so that the memvber a? has a slight longitudinalachustment.

The front end as of themember 219 is bent at right-angles transverselyto the anvil to form a stop or abutment'for the sheet-metal edge-piece jof'the purse, as shown'in Fig. 3.

Theoperati'on of taking a nail from the magazine and setting'itin placeon the an vil, as above described, being efiected by an 7 operation ofhammering the leather down upon the nail by a downward movement of .the'rod T, both are effected by the same treadle, or other hand orfoot-operated device connectedto a rod Y inconnection with the-followingarrangement: Upon the lower end of the shaft D is screwed the nut dwhich acts as'an abutment; against the'lower endfof the standard C,tolimit the upward movement of the shaft. The lower end ofupward'movement of the shaft D, and the the'rod-T carries a ball-end 6which forms with the inclosing members g and y a balljoint, the members3 and 3 being screwthreaded together as shown and the latter being boredand tapped to receive. the threaded end of the rod Y. A fiber-washer 1actsas a cushion for abutment against the end of the shaft D. When therod Y is thrust upwardly the movement is transmitted through the washer3 to the shaft D and the operations already described by which the nailis manipulated and brought into place are carried out, and when the rodY is pulled downwardly after the carrier E has come back into place themovement of the shaft D ceases and the rod T is pulled down, causing thehammer-arm U to be cle- "pressedand driving the nail I through theleather J By then releasing the tension upon the rod Y, the spring twill raise the hammer-arm U and rod T and restore the parts to theirinitial positions.

There remains to be described the manner in which the nail, having beenset in the edge of the purse, is caused to be released by thenail-holding fingers e and 7c.

The rearwardly extending end of the arm 76* of the member K carries apointed toe k with which cooperates a bolt or latch m, carried on theend of a plate-spring m which is secured by screws m on the side of thepost M. The latch m is so disposed as to be pushed back during thereturn movement of the carrier by the toe 71: and finally to engage withthe latter as shown; but when the carrier begins its nextadvance-moven1ent, it will retain the toe 70 for ashort distance at thebeginning of the movement and thereby cause the fingers e and it toseparate, as illustrated in Fig. 6, so as to release the nail, which isnow held by the edge or" the purse; and the purse having been removed,the fingers will, of course, on the further movement of the carrier,snap together again when the toe it passes off the end of the latch m. IThe further operations upon the nail, con.- sisting in cutting off theend thereof and riveting the remaining portion in place, are notperformed by this machine and form no part of the object of thisinvention.

As an additional means of firmly holding the carrier during thehammering operation upon the anvil, the post M is provided with anextension 771, which passes under the carrier and has a hooked end m inposition to engage the left-hand side of the carrier when it descends,thereby acting as an opposing force to the pressure of the bolt m uponthe arm 70 and preventing any yielding of the latter.

It will, of course, be understood that the foregoing descriptionincludes many details which are not of the essence of the invention, ornot material or necessary thereto, and that others need not be made inthe exact form described, but other equivalent devices may besubstituted within the scope of the invention, as will be readilyapparent to those skilled in the art.
